Over the next three days, Yechen focused on the Rasengan and finally received word of its advancement.
"Ding! Congratulations, host. Your Rasengan has reached basic perfection and evolved into 'Gale • Thousand-Blade Rasengan.'" Gale • Thousand-Blade Rasengan: A manifestation of wind energy, possessing unstoppable cutting and explosive power.
Yechen quickly formed hand seals, then opened his right hand. A rapidly spinning vortex of energy first gathered in his palm, flickering with white light and radiating an intimidating power.
This was the Rasengan's first form: the vortex state.
As Yechen focused his will, the vortex changed. The energy within turned cyan-blue, while its outer edge became razor-sharp, producing a piercing whistle as it spun at high speed.
He carefully sensed its properties. The spinning wind blades along the edge of the Gale • Thousand-Blade Rasengan could slice through steel at will, tear through the air, and form a wide-area storm of wind blades. The energy inside remained completely stable as he channeled more power into it. Its tremendous strength was easy to imagine.
This evolution alone could almost rival Naruto's Wind Release • Rasen Shuriken.
He was still in camp, where testing it would be inconvenient, so Yechen dispersed the Rasengan's energy and immersed himself in training again.

Only later did he learn that the higher-ups were reorganizing their forces, assigning the original teams to a single detachment.
The reason was simple: familiar teammates and familiar faces allowed ninja to fight more effectively.
Thus, under normal, stable conditions, the missions assigned to a squad rarely differed
